Double bass pedal help please.?

I need help with a double bass choice. I need to find a pedal that i can play really fast, and when i say fast i mean like ear raping soul crushing fast.Like to where fast is an understatement. I have some pedals i can kinda play fast on but they arnt cutting it anymore. I play like whitechapple, as blood runs black, and born of osiris type of music. I have been looking at axis x-l2 long boards but they are hella expensive. So just wondering if anyone could inform me on another pedal that could do the job and not cost an arm and a leg. thanks
